Continuing my theme of focusing on human character strengths and virtues and relating them to personality,  I have been doing more reading of the literature and want to discuss three papers today.
First up is Shyrack et al’s recent paper that again explores the factor structure of VIA-IS and finds support for a 3 More >Rating: 0.0/10 (0 votes cast)

Character strengths and virtues: a 5/8 factor structure?

by sandygautam in The Mouse Trap

Image via Wikipedia

Positive psychology is based on the premise that it is equally important to study what is good in life as it is to study what goes wrong. Positive psychology thus focuses on building and capitalizing on existing strengths of people while not focusing too much on their weaknesses, which has been focus More >Rating: 0.0/10 (0 votes cast)

How Shoes Can Change Your Life - And Your Skeleton

by Isabelle Winder in Going Ape

A cross-section of a foot inside a shoe. Taken by Mattes, and downloaded from the Wikimedia Commons 26/03/2010.You might think that shoes can only change your life if you are a sex-and-the-city type shoe lover, spending huge amounts of money on designer footwear. And for most of us, that kind of dedication to shoes is fairly incomprehensible - after all, they're just things to wear to keep your feet safe from broken glass and tarmac, right? Wrong....In fact, footwear doesn't just change your lif........ Read more »

UPDATE : Bi-Directional Optogenetic Control

by AndrewHires in Brain Windows

The Deissseroth lab has released an updated version of their optical neuronal silencing gene Natronomonas halorhodopsin. In Molecular and Cellular Approaches for Diversifying and Extending Optogenetics, Gradinaru et al review current optogenetic methodology, and introduce eNpHR3.0-2A-ChR2, a genetic vector whose expression allows both action potential silencing and firing via illumination. This vector uses post-translational cleavage (via cis-acting hydrolase elements) [...]... Read more »

Self-destruction of the mirror neuron theory of action understanding

by Greg Hickok in Talking Brains

Rizzolatti & Sinigaglia's new Nature Reviews Neuroscience paper on the mirror system is effectively an admission that the mirror neuron theory of action understanding is wrong. The original is idea was interesting: we understand actions by mirroring those actions in our own motor system. But this is no longer the case according to R&S:By matching individual movements, mirror processing provides a representation of body part movement that might serve various functions (for example, imitation), b........

On the Phenomena of Lightning

No free lunch in the Land of Cockaigne

by Lucas in thoughtomics

Life is hard for free-living microbes. Many of them undertake great efforts to obtain their energy, some get it directly from sunlight while others derive it from unusual compounds. To them, living inside an animal gut must be like living in some mythical land of plenty. Consider the luxuries! The lucky resident of a [...]... Read more »

Begging meerkat pups

Learning about animal behavior never fails to fascinate me, and so it was with great interest that I read a recent paper on how meerkat pups alter their food-begging behavior depending upon the adult meerkat that they are nearest to. {1} Not all adults are created equal, it seems, in the world of a [...]...

Is Jesus Making You Overeat?

Well, in fairness, Jesus' twelve Apostles should also share in the blame.

An incredibly quirky and yet fascinating study was just published in the International Journal of Obesity which investigated the size of the food and plates that have been depicted in paintings of Jesus' Last Supper over the last 1000 years.

The Mystery of the Siberian Pinkie: When Classification goes Wrong

Biological classification is often misunderstood and misused in the scientific literature and especially in the media:“... birds are dinosaurs” (New York Times, 2010).“Humans are apes” (Dawkins, 2010 in The Australian).“Scientists have identified a previously unknown type of ancient human through analysis of DNA from a finger bone unearthed in a Siberian cave” (BBC News Online).These slogans, popular with the public, are completely misinformed and provide inaccurate information about........

Wrapping up

by iayork in Mystery Rays from Outer Space

How does a viral genome get into a viral capsid?
There are several strategies, but often the viral capsid is built first, leaving a pore open at one corner; and then the viral genome is fed into that pore, getting neatly wrapped up around scaffolding proteins like a spool of thread.
Herpesviruses follow that strategy, and here’s [...]... Read more »

Intelligence a matter of the right connections

by Kevin Mitchell in Wiring the Brain

What makes some people smarter than others?  Is intelligence innate?  Is it under genetic control?  Is there something different about the brains of people with high versus low intelligence, and if so, what is the nature of the difference?  Some answers to these important questions on this often touchy subject are emerging.   Many would bristle at the very notion that some people are “smarter” than others, if that is meant to imply an innate difference in ability.  There is however a........

Large, longitudinal study finds tentative links between internet use and loneliness

by BPS Research Digest in BPS Research Digest

Internet use is growing at a phenomenal rate and much ink has been spilled by commentators forecasting the psychological consequences of all this extra web-time. A lot of that comment is mere conjecture whilst many of the studies in the area are cross-sectional, with small samples, producing conflicting results. The latest research contribution comes from Irena Stepanikova and her colleagues and involves a massive sample, some of whom were followed over time. The results suggest that more time o........
